The pump andA driving mechanism therefor are mountedhpon abracket plate 1l. The bracket platel 11 is ivotally mounted upon a post-12, upon W ich is formed a fixed coll-.ir flange 14 and a pivoted collarflange 15. The collar flange 15 is pivoted to the ilange 14 by means ofa pivot pin 16 at one side of the plate 13, and is secured to a post 1Tby means of a screw bolt 1S, as shown best in Figs. 2 and 3 of; thedrawings. The collar flanges 14 and 15 are shaped` interior-ly Vto fitthe wrench vhead A of a cap Anut for holding the Wheel on the axle of.the automobile. l.

Where the cap nutof the automobile is unusual in-size a special cap B,as shown in Fig. 4, is provided. The cap B has' a wrench head A shapedin form and 'size to correspond with the standard wrench heads, whilethe screw portion ofthe eapB is enlarged or contracte-d to suit-thescrew thread of the hub to which it is to be Vatt-ached. lli/There thepurchaser of a puni )ing mechanism constructed Yand arrange inacoordfance with the present invention has an automobile, the cap n uts whereofdo not 'lit the flanges 14 and 15, the discrepancy may be overcome byproviding the special cap B The post 12 is held rigidly 'upon the plate13 by means of a squared end 19 of the bolt 20. The external end of thebolt .20 is scrcr-r threaded to receive a nut Q1. The nut Q1 bears 4upona key plate 22, the boss Q3 .of which shaped to ya square section, asSeen in dotted lines in Fig. 2. The post` lf) 1s nhamberediiiteriiieiliate the jeuds thereof,

has lin `.view the post 12 `and and is turned to form a cylindrical bodyto provide a rotary bearing for the bracket plate 11 and a gear whee 24.Bearing linings and 26 are provided for, the plate 11- -v the collar 27is secured in position upon the post 12, the plate 11A andv membersconnected therewith' and the gear 24 are secured to the post 12 as' onedistinct machine element, which may be removed from the plate 13 andparts connected therewith by removin the nut 21 and plate 22 and liftingthe sai the plate 22 rom engagement with the nut 21. 'This operation isperformed when, as will be hereinafter described and as shown in theaccompanying'drawings, the pump is disposed upon the Wheel whose tirelsbeing inflated. at the time.

Pivotally mounted on the outer-end of the plate 11, and by means of avpivot-pin 23, is an air pump, cylinder 29. The cylinder 29v is providedwith a cap 30, through the cylindrical perforation wherein is, passed apiston rod 31 Whereon is mounted a piston 32.: A'The-piston '32 isconstructed in the usual manner to provide a valve,.the operation of'which passes the airfrom the. back of the said piston into the chamberforward of the' piston, the air being admitted tothe upper end of thecylinder 29 througha perforation 33, as seen best in Fig. 3 of thedrawings. The piston rod 31 is secured pivotally by mea-ns of a screw 34to a crank arm 35. The

' crank arm 35 is integrally formed' with a gear wheel-36. The gearwheel 3G is rotaf tively mounted upon a screw bolt 37, and is meshedwith the gear wheel 24.

W'hen-'constructed as thus far described the pump .is operated fr om thedrivin sh aft of the automobile, and from the Y r-iving Wheel thereonmounted. To connect the post- 12 with the gear wheel 24 the hub ofthegear Wheel is provided with a gooved .extension 38, in the groovewhereof is pivotally mounted a latch arm 39., The latch arm 39 is heldin position, operative or in" operative, by a fiat spring 40. Whenthelatch 39 is thrown fro-m the-position shown in Figs. 2 and 3 of thedrawings to engage a groove41 in the' plate22. the gear Wheel 24 iscompelled to rotate in unison with the plate 22, which is rotated by thepost 12,'

plate 13 and flanges 14and 15, these being vsecured fixedly to thedriving Wheel C of the automobile.

arts connected therewith andl The nipple 42 is usually connected bymeans of a flexible hose pipe 43 with the inner tube of one of the tiresof one Vof the wheels of the automobile, said wheel being other than theWheel on which the pump is mounted when disposed as shown in Figs. lv to3 inclusive.

When it is` desired to iniiate the Wheel upon which the cylinder 29 ismounted, the

arts are disposed as shown in Fig. 4 of the rawings. To. transfer theparts from the position shown 'in Figs. 1 to 3 inclusive to the positionshown in Fig. 4, the nut 21v is removed and the post 12 and all thememibers connected therewith, including the plate 22, are removed fromthe bolt 20 and reversed end for end and replaced uponthe said bolt 20,the plate -22 being omit-ted.

The plate 22 is subsequently placed upon the.

bolt 20, the squared boss 23 of the said plate being inserted in theperforation formed in the post l2, which perforation formerl engaged thesquared section 19 of the bo t 20. ,The nut 21 is -then replaced and thepum-p is di osed as shown in Fig. 4 of the drawings.

odeliver the air from the cylinder 29 to .thetire of the Wheel on whichthe said pump 1s mounted, it becomes necessary for the plate 11 andparts mounted thereon to gyrate around the alxis of the wheel C tomaintain the relative relation between 'the' pump and the hose pipe 4,3.To rotate the gear wheel 36 under these conditions -it becomes necessaryto hold in arrested position the gear wheel 24. It is for this purposethat `there is extended from the side of the hub of thel gear wheel 24'.an arm 44.

vThe arm 44 serves'a ldual purpose, to wit, that of maintaining thestationary position of the gear wheel 24 and to form an enga-g-A ingmeans for the hand lever 45. As shown in Fig. 4 of the drawings, thehand lever 45 is employed to hold. the gear vWheel 24 in stationaryposition, the lever being anchored hy means of' a rod 46. to the frameof thee automobile.. As shown, the lever 45 is connected to the rod 46byl an eyelet 4T of the said rod being assed through the .perforation 48formedin the end of the said lever 45. (See-Figs. 3 and 4 of thedrawings.)

To connect the plate 11 withthe post 12 there is provided a. latch 49pivotally mounted in brackets 50.W The latch-49 is `vpivoted at 51, andwhen rotated upon its pivots falls I into a groove .52.provided in thehase flange of the post 12, as best seen inFigs. 3 and 4 of thedrawings. l/Vhen the saidlatch 49 is disposed in the groove 52 the4 post12` and the plate l1 are mutually locked, and the plate 22 and partsconnected therewith are rotated about the axis of thewheel (l.I

The lever @l is provided to supply a want for a hand ii'iaiiipulatedpump. he oonlstruction as described, yand particularly as shown in Figs.l to 3 inclusive, may be einployed for hand manipulation by engaging thelcver 4.5 with the arin 44. For this purpose the arm 44 is provided with'n flat spring 53, having formed at the end thereof a latch head 54,which latch head 54 overstrikes a hooked end 55 formed on the inner endof the ylever 45. The levergt is further provided with guide hooks 56,56 by which it is guided as the lever 45 is slid over the arin 44. Thelever 45' is` provided with a hand grip 57i', a screw threaded shankwhereof inserted in a tapped hole formed in a boss 58 intermediate theends of the said lever.

lIl: it be desired the screw threaded end o f the grip57 may be extendedto pass Vthrough the perforation 48 to receive a clamping i screw nut atthe opposite side of the lever 45.

If the conditions of operation of the now hand operated pump be that thewheel C is Seated on the ground, the latch 39 is raised, as sliowninFig. 3 of the drawings. Inthis position the. gear wheel 24 ismanipulated `without turning orendeavoring to turn the plate 2 2 andparts connected therewith, the

lplate '11 beingy anchored h v means of Va chain 59, the cylinder 2S) isheld while the piston 32 is reciprocateifl therein, the gear wheel 24being rotated by means of the operator turning the same, with the leverholding and 'as alitnfecdeswdied, the nipple Ll2 is coni'iectcd h vmeans of a pipe. Rl with a passage S2 `formed Vin the post 11%. Thei'iassage S2 is extended lengthwise of the said post, hav- .iig auopt-iiii-j :it the end opposite from that which the pipe tit isconnected with. .so that the .pipe 43 may be connected at the eiiduol'the post adjacent' the. wheel (l. ln thi.`4 niaiuier the. air ascompressed iii the. cylinder 2i) is transferred through the post 1Linside the' rotary path of the plate 1l and i-,vlinder 29.

ln l"r 5 and t of the dra wing` is shown .modified form ofthe invention.'l`htl i i u d it'iea t ion consists Aprnnarily pivot post (it) isformed integrally with the plate til., which corresponds to the plate 13of the structure illustrated iu Figs. 1 to l inclusive of the drawings.Upon the pivotpost (i0 is lliivotallv mounted 'a bracket plate (i2,resembling in function and structure the bracket; plate 11. Supportedbythe bracket plate 62 is a pump G3, which is pivotally mounted on theplate 62 by means oil a pivot screw G4. The piston rod (i5 of ,they pump63 is pivotally connected with a crank arm 6G. The crank arni 66 is)rovided with a pivot cup 67, on the si es whereof are ormed extensions68, between the members whereof is formed a slot (it). The slot (it). isprovided to'receive a latch 70. The latch is pivotecl at 71 inextensions 72 correspondlng in shape to those shown as (i8 in Fig. G ofthe drawings. lVhen the latch 70 is dropped to the position as shown inFig. 5 of the drawings, a collar 73 and the pivot cup 67 are heldrigidly together. The collar 73 is held by a. key 74 in non-rotativerclation to the post (i0. The crank arm 66 and cup G7 are provided witha pivot scr'ew 75, the screw threaded section 7o 'whereof is driven intoa suitable perforation formed in the center of the cup 6T. lVheii sodriven the pivot is secured by means of a pin 7T. flhe outer end-of thepivot screw 75 is reduced and threaded to receive a nut 78 whihis heldin locked position by a pin 7 The bitter end of the crank arm (36isprovided with a. squared extension 80. The extension` 80 is providedto receive a lever for manually cranking, the lever being formed in amanner similar to the lever l5, having, instead of the connecting headshown in connection with the said lever l5 in Figs. *2 and 3 of thedrawings, a squared socket of usual construction.

`When the. modified foi'in shown in Figs. 5 and is monntedin operativeposition on the driving wheel of an automobile, the plate (r2 is heldnon-rotatively byl being anchored to the body structure of theautomobile or by heilig braced against the adjacent ground. Then thepump 'ismanually operated the hand lever corresponding to the'lever 45is connected with the squared vextension 80 of' the crank arm GG, thelatch 70 is thrown to the position shown in dotted lines nFg, 5, out ofengagement with the pivot cuptl'. T he. crank arm 6F may now be turnedwithoutV influencing the wheel or the plate G1 which is fastened to thecap n ut of the said wheel. lVhen, however, it is desired to 0perate thepiiinp by means of the wheel to4 which the plate 61 is connected, themanually operated lever referred to is. removed -and the latch TO .isthrown to the, position shown in full lines in Fig. of the drawings,

locking thereby the collar 73 and the pivot t'np t in holding relation.lihen the. wheel ijn lli-.it the i o'bthc automobile is rotated, thepost 60 and the collar 73 are likewise rotated. When the latch 7() isthus thrown, the crank arm 66 is also rotated in unison with the'saidwheel to operate-the piston rod 65 and the pump 63.
